Don't much care for the whole "I will no longer do this Normal Thing if I suspect someone watching me might have a fetish for it." like, y'all this is why people are censoring their damn feet in otherwise-innocuous photos.
Hate to break it to you but everything is a fetish. Drinking water? Fetish. Eating? Fetish. Sneezing? Fetish. Clearing your throat? Fetish. Burping, farting, pissing, shitting, walking, sitting, standing, having your mouth visible when you talk, making certain mouth sounds, your accent (yes yours), your skin color (yes yours), makeup, lack-of-makeup, smelling bad, smelling good, smelling neutral, hair, lips, noses, eyes, ears, chins, shoulders, necks, armpits, elbows, fingers, chests, stomachs, backs, hips, thighs, knees, knee pits, ankles, toes, soles - all fetishes. Like it or not someone somewhere will Perceive You and they will Like What They See.
And they will be silent and normal about it because guess what? Fetishes are normal and most people know how to conduct themselves around others tactfully. We only ever find out about specific fetishes as they relate to us in particular when someone is choosing to be decidedly Not Normal about it, so we assume everyone who has those fetishes is a tactless weirdo. Rookie mistake. I guarantee some of your friends have fetishes for innocuous non-sexual things too, and it doesn't make them some kind of pervert creep.
